Description
Technical Field
The invention relates to the technical field of aerostats, in particular to a high-altitude balloon dispensing device and a high-altitude balloon dispensing method.
Background
The aerostat is also called as a high-altitude scientific balloon, and is an unpowered aircraft which is lifted off by means of buoyancy gas and can fly at the altitude in the nearby space under the action of wind power. The high-altitude balloon has the advantages of high flying altitude, long dead time, low manufacturing cost, short preparation period, easy flexible deployment and the like, thus having great development value in civil and military fields and becoming a carrier which is driven by aircrafts such as rockets, artificial satellites and the like and performs various space science and technical researches.
As a mature type of high-altitude loading platform, the size of the high-altitude balloon is determined by the weight of the load and the height of the residence. At present, the design space height of the high altitude balloon is about 18km to 40km, but the weight of the carried load is two extreme: the system comprises a large scientific instrument with the weight of more than 500 kg and even several tons, and a communication load, a investigation load and a weather detection instrument with the weight of about several kg or more than ten kg. Therefore, the volume of the balloon designed by the former is usually up to hundreds of thousands of cubic meters, which belongs to heavy-load high-altitude balloon, while the balloon designed by the latter is mostly thousands of cubic meters, which is a medium-sized and small-sized high-altitude balloon. From the application potential, the small and medium-sized high-altitude balloon is simpler and cheaper than the heavy-duty high-altitude balloon, has wider application range, can be used in the fields of reconnaissance, communication, weather detection, pollution monitoring, urban management and the like, and has important development value.
The release process of the high-altitude balloon is influenced by the release mode and the field operation on one hand and is easily influenced by site meteorological conditions on the other hand. Currently, balloons mainly face several problems during the release process: (1) The balloon is a wind body in the ground inflation process, and can shake under the influence of wind speed and wind direction; (2) At the moment of balloon release, the load weight is large, so that the collision overload of the nacelle and the balloon is large, and the risk of damage is high; (3) The required guarantee resources are complex, including hauling and arrangement of the bag bodies and equipment before distribution, the ground inflation process, the number of personnel required by command operation and the requirement of tooling equipment are more. Therefore, how to realize the simple, convenient, safe and reliable release of the high-altitude balloon has important significance for balloon flight tasks.
The technical scheme of the air ball dispensing mainly comprises dynamic dispensing/static dispensing/soft dispensing/motor-driven winch dispensing/atypical wind-shield wall dispensing and the like, and specific schemes of various dispensing methods can be seen in patent CN1562702A, CN104890851A, CN107585285A, and the dispensing methods can meet the dispensing operation of various high-altitude air balls to a certain extent. The dynamic dispensing mode is mainly suitable for large heavy-duty high-altitude balloons, the static dispensing mode and atypical wind-shielding wall dispensing are suitable for medium-and small-sized high-altitude balloons, and the winch dispensing and the soft dispensing are both suitable. Various dispensing modes have certain limitations and disadvantages in view of reliability, economy and environmental suitability.
The disadvantages of various high air ball dispensing modes are as follows:
the dynamic release mode is suitable for large-scale high-altitude balloons, needs a special crane and a larger release site, and is easily influenced by weather;
the static release mode is that the nacelle and the balloon can be subjected to larger impact and vibration at the moment of towing and rising of the balloon, and are easily affected by weather;
the soft dispensing mode is characterized in that at the moment of balloon detachment, the balloon and the nacelle are not on the same vertical line, so that the nacelle can swing greatly and is subjected to larger impact and vibration, the cost of auxiliary balloons and helium used is increased, and the balloon is easily affected by weather;
the motor-driven winch is not strong in environmental adaptability in the release mode, and release operation cannot be performed when the wind load of the field is large;
the atypical in-wall dispensing device is suitable for the serial middle-small balloon dispensing, but the system is complex and the device cost is high.
In addition, the dynamic dispensing/static dispensing/soft dispensing modes have the defects of site guarantee, high number of operators and long preparation period.
Accordingly, it is desirable to provide a new high-altitude balloon dispensing apparatus and dispensing method that solve the above problems.

step 2.2, arranging an external power supply, and starting a driving source (4) to unfold the folding support arm (2);
step 2.3, laying a high-altitude balloon (15) at a position with a certain distance from the flat trolley (1), and placing a nacelle (16) at the middle position of the flat trolley 1 while laying;
step three, an inflation stage:
step 3.1, fully unfolding the folding support arm (2) at a preset position, connecting one end of a mooring rope (8) with the rope buckle, knotting and connecting the other end of the mooring rope with a rotary pin shaft (12) of the wire stripper (3), and simultaneously installing a high-altitude balloon (15);
step 3.2, detecting and confirming that there is no interference between the nacelle (16) and the mooring line (8), and that the suspension line (17) and the mooring line (8) are not wound;
step 3.3, filling helium into the high-altitude balloon (15);
step 3.4, after the inflation is completed, ensuring that each stay rope (8) is in a tensioning state, and suspending the nacelle (16) from the flat trolley (1) by a distance of more than 20cm;
step four, a release stage: the electric push rods in the plurality of dispensing assemblies are controlled to synchronously work, meanwhile, the limiting pin shafts (11) are pushed to be separated from the locking blocks (19), the constraint of the rotating pin shafts (12) is released, the mooring ropes (8) slide to be separated from the rotating pin shafts (12) rapidly, and the high-altitude balloon (15) is lifted off with the nacelle (16);
step five, completing the release operation of the high-altitude balloon; the driving source (4) is started to shrink the folding support arm (2) to return to the flat trolley (1), and then the distributing device is supported and transported back to the boat warehouse (14) through the tractor.
8. The method for delivering high-altitude balloon according to claim 7, wherein the ground wind speed of the delivering site in the second step is not more than 5m/s, and if the ground wind speed before delivering exceeds 5m/s, the second step and the third step are performed in the boat warehouse (14), and when the ground wind speed of the delivering site is lower than 5m/s, the high-altitude balloon (15) on the tractor-hauling flat-bed trolley (1) is delivered to the delivering site for delivering operation.
9. The method according to claim 7, wherein the length of the mooring rope (8) is calculated in advance before the first step according to the ground helium filling volume, the height of the suspension rope (17), the geometric parameters of the flat trolley (1) and the position information related parameters of the folding support arm (2), and the calculated length is actually 1.2 times.
